If only Carl could see what today's technology and astronomical knowledge is like... R.I.P Carl. :(

I love the video an Carl Sagan, but I have to point this out: the shadows could also e different on a flat world, just like a single light in a room casts different shadows.

@ksthebest Depends how far away the source of light is, for a candle, you are correct, but with the sun, the rays are as close to parallel as matters in this matter.

[ksthebest]

@butlerlog Correct me if I'm wrong because I did not investigate this, but I'm assuming the people of the time did not know nearly how far away the sun really is.

@crocfme Absolutely. Love him.

Scientists, explorers and teachers have always been humankind's true leaders; Sagan was all three. An extraordinary man...
